Using Blinder Lights Correctly to Build High-Energy Moments

A blinder is a bright, wide fixture pointed at the audience that fires in short hits on the biggest moments of a song or set. Used correctly, it lights up the whole crowd for a beat or a bar and then drops away. If it stays on or fires constantly, people mostly just squint. This guide covers what blinders are, where the hits belong, how to program and aim them, how to keep the crowd comfortable, and how to get the same kind of hit from PARs and COB fixtures if you do not own dedicated blinders.

What a blinder is

The classic audience blinder is a 2-lite, 4-lite or 8-lite fixture: a row or block of PAR36 tungsten lamps, often the 650 W DWE type, mounted at the stage edge or on upstage truss and aimed at the audience. Tungsten blinders give a warm white of about 3,200 K. Because a filament takes a moment to cool, the light glows down instead of snapping off, and that warm afterglow is a big part of the look.

LED and COB blinders now do the same job with far less power. Many include a "tungsten" or "halogen" mode that copies the warm color and the slow fade-out, and some add RGB or adjustable color temperature.

A blinder is not a strobe. A strobe fires very short flashes again and again. A blinder hit is one bright moment held for a beat or longer, and the fade-out is part of it. A blinder is also not a wash light: washes light the stage, while blinders light the people watching it.

Power draw: plan for it

Tungsten blinders draw a lot of current, even if they only fire a few times an hour. A held cue can sit at full for several bars, so plan circuits for the full load:

On a 120 V, 20 A circuit, the usual 80% rule for continuous loads leaves 16 A, so a single 4-lite already exceeds one circuit. In 230 V countries (UK, EU, Australia) the same fixture draws about half the current, but it still needs its own properly rated, RCD-protected circuit. Follow local wiring rules and ask a licensed electrician if the venue power is unclear. LED blinders draw a fraction of these figures. Check the label or manual for the actual wattage.

Where blinder hits belong

Blinder hits work because they are rare. The crowd should feel the difference between the normal show and a hit. Good spots:

• The downbeat after a build or drop. Pull the stage down to dark or a single color for the last bar of the build, then hit on beat one.
• The first chorus entry and the biggest final chorus.
• Band intros and encores. A hit as the band walks out or as the encore starts tells the room something has begun.
• Wedding and party moments. The grand entrance and the first track that opens the dance floor. Keep blinders off during speeches, the first dance and toasts, where faces need soft light.
• The final note. Full hit on the last chord, then fade out slowly with the sound.

As a starting point, plan a handful of full hits per hour, not one per song. Fire at lower levels for teasers in the pre-chorus and save 100% for the moments that count.

Programming blinder hits

Timing

Keep most hits between one beat and one bar. Holding full intensity for eight bars flattens the effect and tires the eyes. Two moves cover most needs:

• Blackout and hit. Drop most of the rig for one bar, then bring blinders and the main look back on the downbeat.
• Stutter build. Pulse blinders at low to mid intensity on the snare hits of a build, then go to full on the downbeat. Keep the pulses well below strobe speed.

Intensity and fades

Leave blinders at zero, or at a faint glow, as their resting state. Snap them on and give them a short fade out, around half a second to a second, which reads like a tungsten afterglow even on LED fixtures. If your LED blinders have a tungsten-emulation mode or dimmer curve setting, try it; it smooths the low end of the fade.

On a simple DMX controller

On a basic 192-channel DMX controller, store the blinder hit as its own scene with the blinder channels at full, and keep your base look in another scene. Practice recalling the hit right on the downbeat. If your controller or PC software has flash or bump buttons, assign the blinder channels to one. The hit then lasts exactly as long as you hold the button, which is the easiest way to time it to the music by hand.

Color

Warm white is the traditional choice and flatters faces in photos. Cold white feels harsher, which suits some electronic sets. With RGB-capable fixtures you can hit in a color, but white usually reads as the biggest moment because it is the brightest output most fixtures have.

Placement and aiming

• Mount blinders upstage or at the sides, above the performers' heads, and tilt them down across the crowd. The light then reaches the audience at an angle, not straight into the eyes of the front row at head height.
• Aim for the middle of the crowd, not the ceiling or back wall. The goal is to light people.
• Avoid floor-level blinders aimed into faces from a meter or two away. That is the most uncomfortable position for the audience.
• Secure any fixture hung overhead with a clamp and a safety cable.
• Check the hit from the crowd's side during setup. If it is painful at the front, lower the level or change the tilt.

Audience comfort and safety

• Keep hits short and occasional. Long periods at full intensity aimed at people cause discomfort and afterimages.
• Be careful with fast flashing. Rapid flashing can trigger seizures in people with photosensitive epilepsy. A common guideline, used in broadcast and web accessibility rules, is no more than three flashes per second. Avoid long runs of fast blinder chases, and post a flashing-light notice where the venue requires one.
• Go softer at events with young children or older guests.
• Do not use narrow beam fixtures as blinders aimed at eye level. A beam concentrates its output into a small spot, which is much harsher than a wide blinder at the same distance.

No blinders? Getting a blinder-style hit from PARs and COB fixtures

Plenty of small rigs have no dedicated blinders, and you can still get a convincing hit with wide fixtures you already own:

• COB PARs and COB spotlights. A single large COB source behaves most like a blinder cell. Mount it upstage, aim it at the crowd and program the same short hits.
• RGBW PARs at full white. Set every color channel to full for the brightest white the fixture can make. Several PARs upstage, fired together, give a usable crowd hit in a small room.
• Beam moving heads. Keep them sweeping above the crowd for the build and let the wide fixtures do the audience hit.

UKING does not currently sell dedicated audience blinders. In small venues, ZQ01496 200W COB PAR or ZQ09012 200W dual-color RGBWA+UV COB spotlight can play the blinder role when aimed at the crowd. Each of these puts out less than a multi-cell tungsten blinder, so use two or more for a larger room, and add a short fade-out to mimic the tungsten glow.

FAQ

What is a blinder light used for?

A blinder lights the audience in short, bright hits at key moments in the music, such as a drop, chorus or band entrance. It makes the crowd part of the picture for a moment and marks the peaks of a show.

Are blinder lights bad for your eyes?

Brief hits from a properly aimed blinder cause temporary dazzle and afterimages, much like a camera flash. The problems come from long exposure, close range and low, eye-level aiming. Keep hits short, mount the fixtures high, and avoid fast flashing.

What is the difference between a blinder and a strobe?

A strobe fires very short flashes repeatedly. A blinder gives one bright hit of a beat or longer, with a fade-out, and is aimed at the audience. Many LED blinders include a strobe channel, but that is a different effect.

Does UKING sell blinder lights?

Not as a dedicated product. UKING COB PARs and COB spotlights can be programmed for blinder-style audience hits in small and medium rooms.
